Example tools

tip

The example tools are built by adding an option --all to the cargo build command. They are generated and saved in the directory ./target/release/.

Server​

Run the quic server​

./tquic_server -c cert.crt -k cert.key -l 127.0.0.1:8443

The server is configured to listen on the address 127.0.0.1:8443 and act as an HTTP/3 file server.

The test certificate cert.crt and private key cert.key can be found in the directory ./src/tls/testdata/. They can also be generated using the following commands:

openssl genpkey -algorithm RSA -out cert.key -pkeyopt rsa_keygen_bits:2048
openssl req -new -key cert.key -out cert.csr -subj "/C=CN/ST=beijing/L=beijing/O=tquic/CN=example.org"
openssl x509 -req -in cert.csr -signkey cert.key -out cert.crt
